I hope this message finds you after so many years and that you can make use of it.
John D Gillis, son of Robert and Jerusha Gillis, b. 2 August 1779 in Hebron, Washington Co., NY, married Mary Ann Smith, b. Ireland about 1797. They lived for a time in Washington Co., NY, then moved to Victor, Ontario Co., NY.
It's important to note that Mary Ann had at least three siblings; Rosannah, b Ireland 1791; Michael, b. NY 1800; Edward O, b. NY 1808. Edward O was an early pioneer accredited as one of the first settlers of Eaton Co., MI and its possible that this is why the Smiths and Gillis' removed to Western NY. Michael and his family lived in Shelby, Orleans Co., NY; Rosannah married Levi S Bishop and later in life moved their family from Saratoga Co., NY to Victor, Ontario Co., NY.
Letters were exchanged between the Gillis, Smith and Bishop families proving a close relationship throughout the years. From my understanding, the Gillis' remained primarily in Ontario Co., NY, but spread throughout Western NY into Monroe, Livingston and Orleans counties as well. I don't know much about any of them before settling in Western NY, as records are scarce from that early period.
Please feel free to contact me with any questions. I'd be very interested in making a connection with you concerning these families. email: firstname.lastname@example.org
